In the edited audio that went on the air, George Zimmerman sounds
like he thinks Martin is up to no good because Martin is
black.

Zimmerman: This guy looks like he’s up to no good. He looks
black.

One thought seems to flow into the next. Martin looks like
he is up to no good, presumably, because he is
black.

But the actual transcript of the 911 call is this:

Zimmerman: This guy looks like he’s up to no good. Or he’s on
drugs or something. It’s raining and he’s just walking around,
looking about.

Dispatcher: OK, and this guy — is he black, white or Hispanic?

Zimmerman: He looks black.

So in the actual version, Zimmerman says he "looks black" when he
is asked to describe Martin's race, not when he is trying to
justify why he thinks Martin is "up to no good."

Now of course, Zimmerman may have all sorts of heinous attitudes
about race. But NBC seemed to be stacking the deck with its
viewers.

Much of the public discussion over the past week has
settled on how conflicting facts and interpretations call into
question whether Zimmerman acted justifiably or criminally.
That’s a process that’ll continue. But one set of facts is
ironclad, and that’s the back-and-forth between Zimmerman and the
dispatcher. To portray that exchange in a way that wrongs
Zimmerman is high editorial malpractice well worthy of the
investigation that NBC is now mounting.
